So don't allow Uprobe on such prefixed instruction. # # There are two ways probed instruction is changed in mapped pages. # First, when Uprobe is activated, it searches for all the relevant # pages and replace instruction in them. In this case, if that probe # is on the 64-byte unaligned prefixed instruction, error out # directly. Second, when Uprobe is already active and user maps a # relevant page via mmap(), instruction is replaced via mmap() code # path. But because Uprobe is invalid, entire mmap() operation can # not be stopped. In this case just print an error and continue. # # Signed-off-by: Ravi Bangoria <ravi.bangoria@linux.ibm.com> # Acked-by: Naveen N.
